HEATING AND SMOKE-CONSUMING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 515,718, dated February 27, 1894.

Application filed May 16 1893. Serial No. 474,418. [No model.)

T0 caf/ZZ whom it may concern.-

Be it known that I, GARRETT WALLACE .POOLE, a citizen of the United States, residing in Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Heating, Ventilating, and Smoke-Consuming Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. i This invention relates to a new and useful improvement in combined heating, and smoke consuming apparatus, and it consists in the combination and arrangement of parts and details hereinafter set forth and claimed.

My invention is illustrated in the accom` panying drawings, in which- Figure l is a side elevation of the interior of a building and of my approved apparatus in position. Fig. 2, is an enlarged side elevation partly sectioned of the chamber designed to receive the unpuriied smoke from the furnace. Fig. 3 is a similar view of the chamber 1n which the smoke is purified. Fig. 4 is a cross section taken on the line x-.r of Fig. 2 and Fig. 5 is a cross section taken on the line y-y of Fig. 3.

`In said drawings A represents an engine of usual construction, communicating motion through shaft B and pulleys to a fan or blower J. At one side of the engine A is arranged the furnace c., within which an ordinary boiler 1sl placed. Leading from the dome of the furnace a is the fuel or smoke pipe b provided with a damper c. This smoke pipe b enters a chamber cl and smoke leaves said chamber d through pipe f provided with damper h, which pipe j' enters the usual chimney g (see Fig. l). The blower j is provided with two outlet pipes i and la, the lower one (lo) of which enters the furnace abeneath the grate bar m thereof, and is provided with a damper la. The upper pipe i is provided with a damper t and extends through the chamber d into the funnel shaped pipe n, which has an opening into said chamber d. This pipe n is provided with a damper u and enters a chamber 0, preferably at the lower end thereof. From said chamber o leads a pipe p into the furnace a below the grate m, while a branch tube q enters said furnace above said grate, as clearly shown in Fig. l of the drawings. Said pipesp and gg are provided with dampers p and q respectively.

From the pipe n and on either side of its damper n lead the pipes fr and s, provided with dampers 'r' and s respectively. These pipes fr and s are respectively the inlet and outlet pipes to and from a system of heating pipes c and radiators t. The pipe s has an outlet v2 into the open air, provided with a damper fu', see Fig. l.

Leading from the steam dome c of the boiler is a pipe c', which terminates inside the chambers d in a semi-dome shaped case d the under wall d3 of which is perforated as at d4 (see Fig. 2). Arranged on the side of the chamber d above the mouth of pipe b is a detlecting plate d2 for the purpose hereinafter described. Also leading from said steam dome c is another steam pipe o2 entering the chamber 0 and terminating in a cylindrical chamber 05, having an upper wallo anda lower wall o2. The lower wall is perforated by minute orifices o3. This chamber o5 separates the chamber o into two compartments, and is placed below7 the mouth of pipe p (see Fig. 3). Communication between the two compartments of chamber o is effected by tubes o4 extending through the walls o o2 and the entire chamber o5.

In operation, when the apparatus is to be used for smoke consuming, the dampers i', n', e and q are opened, while the dampers a", s', p and k are closed. The damper his opened wholly or partly as may be necessary to allow excess of smoke from the furnace to escape into the chimney g. In this position smoke from the furnace d ascends into chambers d, wherein it is sprayed by minute jets of steam from orifices d4 of the semi dome shaped chamber d', and in this chamber d the smoke is defiected by plate d2 toward the wall d3 and toward the outlet pipe n. Air is now 'forced into the funnel shaped end of pipe n Ien pipe fn serves to draw in the sprayed smoke from the chamber d. The air and smoke is then forced through pipe m (dampers r and s' -being closed and 'n' open) into the chamber 0 below the cylindrical partition o5. The compartment below said partition o5 is preferably filled or partly filled with sawdust (not shown) or similar matters, through which the air and smoke are strained. In this compartment the combined air and smoke are sprayed by steam from the orifices o3 in the under wall 02 of the partition 05, and the sprayed air and smoke are then forced through the tubes o4 into the upper compartment from whence it enters the pipe p. The combined air and smoke is then forced through pipe q (damper q being open and damper 1o closed) into the fire chamber above the grate m, where it is consumed.

The products of combustion can be utilized for heating purposes, in which case the dampers 1l', e, fr', s', and p are all opened to their full extent, while the dampers n and q are closed. The damper 7L is opened to an extent only to allow an excess of smoke to escape from the furnace. Supposing the dampers are in the position above described, air is forced from the blower j through pipe fr' into pipe n where it mingles with the hot air of chamber d which comes from the furnace, by reason of the well known siphon action in said tube fn. The damper n being closed and damper r open, the heated air is next forced through pipe r into the heating pipes fu and radiators fwithin the building. From the building the heated air passes through pipe s (damper s being open) into the tube n on the other side of the damper n. The spent hot air is then forced through chamber o and through pipe p below the grate and serves to increase the blast or draft. When an increased blast is required the damper 7c may be opened wholly or partly, and air directly from blower j, fed below the grate m.

It is manifest that with proper regulation of the various dampers both heating and smoke consuming may be performed at the same time by my apparatus.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a smoke consuming apparatus, the combination of a furnace, and the steam dome of its boiler a chamber adapted to receive the smoke from said furnace, a blower and siphon adapted to suck the smoke from said chamber and to combine the same with air in the siphon, with a system of pipes leading from said siphon to the lire place of the furnace, and with a pipe leading from the steam dome to said chamber, all arranged so that the combined air and smoke after the latter has been sprayed with steam in the said chamber is forced from said chamber through the siphon to the fire place of the furnace, and above and below its grate bar substantially as described.

2. In a smoke-consuming apparatus the combination of a furnace, and the steam dome of its boiler a chamber adapted to receive the smoke from said furnace a blower and siphon adapted to suck the smoke from said chamber and combine it with air in the siphon, with a purifying chamber in communication with said siphon a system of pipes leading fromber interposed between the furnace and its` chimney and provided with a steam spraying wall adapted to spray the smoke in said chamber and a deflecting wall adapted to deIiect the smoke toward said steam spraying wall and toward the outlet of the chamber, substantially as described. t

4. In a smoke consuming apparatus, a purifying chamber for combined smoke and air, consisting of anupper and lower compartment separated by a cylindrical hollow partition in communication with a steam chest said cylindrical partition having on its under face a series of minute orifices and being perforated with a series of tubes forming a communication between the two compartments substantally as described.

5. In a smoke consuming apparatus, the combination of a furnace and the steam dome of its boiler, a chamber adapted to receive the smoke from said furnace, a blower and siphon adapted to suck the smoke from said chamber and to combine the same with air in the siphon, with a purifying chamber in com'munication with said siphon, a system of pipes leading from said purifying chamber to the [ire place of the furnace, a pipe leading from the steam dome to the chamber and a pipe leading from said steam dome to the purify-` ing chamber, all arranged so that the smoke after being sprayed with steam in the chamber is combined with air in the siphon, and is forced through the purifying chamber, (where it is again sprayed with steam) into the fire place of the furnace, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 19th day of April, 1893.

GARRETT WALLACE POOLE.
